We've been promised an exciting future with gadgets perpetually powered by magical fuel cells, and a company called Lilliputian Systems is taking the first steps towards tomorrow with its fuel cell-based USB charger that will soon be available from Brookstone.

Unlike backup batteries which have to occasionally be plugged into a wall for hours like your various devices, the fuel cell charger uses small cartridges—about the size of a cigarette lighter—filled with butane to generate power. Pricing for the charger hasn't been revealed just yet, but the replacement fuel cartridges are expected to sell for roughly the same price as a Starbucks coffee. Possibly forcing you to choose between your addictions: caffeine, or browsing Facebook.

Each cartridge is able to fully recharge a dead iPhone from ten to fourteen times, which helps make the cost of the replacements more reasonable when you break the down the per-charge price. The charger should particularly appeal to those who travel a lot, since the fuel cartridges are allowed on planes just like cigarette lighters. And a few dollars to recharge your phone again and again is a far better solution than scouring airport lounges looking for an available outlet. [Lilliputian Systems via Cnet]
